The integration of electric vehicles into power dis tribution systems is increasing worldwide, driven by government support and sustainability goals. This study examines the perfor mance of a distribution network with detail-modeled residential loads under varying penetration of electric vehicles and evaluates their impact on peak demand, voltage deviation, phase unbalance, and power losses. The findings show that uncontrolled charging significantly increases evening peak load and causes voltage drops exceeding the ±10% limit at high penetration levels, while controlled charging effectively mitigates these issues. The results could serve as a basis for distribution system operators to apply controlled charging as a cost-effective measure to manage the growing demand from electric vehicles without extensive grid reinforcements.
